4 Claims.

This invention relates to machine guns, and more particularly to an improved mounting therefor.

An object of the present invention is to provide a mounting for a machine gun which includes means providing for the continuous oscillation of the gun in a horizontal plane.

A further object of the invention is to provide a mounting for machine guns which includes means for providing for a continuous rocking movement of the gun in a vertical plane in addition to a continuous oscillating movement of the gun in a horizontal plane.

The invention, together with its objects and advantages, will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view illustrating the application of one form of gun mount;

Figure 2 is a top plan view of the gun mount;

Figure 3 is a sectional View through the mounti Figure 4 is a fragmentary detail sectional view showing the manner of securing the gun on the mounting;

Figure 5 is a fragmentary perspective exploded view showing certain elements hereinafter more fully referred to;

Figure 6 is a fragmentary bottom plan view of a cylinder forming part of the mount;

Figure 7 is a detail sectional view showing one of the ear segments;

Figure 8 is a view similar to Figure 1 illustrating a slightly modified form of the invention, with certain parts broken away and shown in section;

Figure 9 is a fragmentary detail sectional view illustrating certain details hereinafter, more fully referred to.

Referring to the drawings by reference numerals, and particularly to the form of the invention shown in Figures 1 to 7, it will be seen that the improved machine gun mount comprises an electric motor indicated generally by the reference numeral 5, and in accordance with the present invention the casing of the motor 5 is constructed so as to provide at one end thereof a gear box. Said casing of the motor is also formed at opposite ends thereof with apertured attaching brackets '5 through the medium of which and suitable fastening elements the motor may be secured to a suitable support.

The gear box 6 is suitably provided with aligned bearings 9 and it, respectively, in which are journaled the ends of the shaft II that extends at right angles to the shaft of the motor.

Suitably mounted on the shaft II for rotation therewith are spaced gear segments I2 and I3 which are successively engaged by a gear seg- 5 ment I4 provided on one end of the armature shaft of the electric motor. It will thus be seen that when the gear segment I4 is in mesh with the gear I3 the shaft I I will be rotated for a fraction of a revolution in one direction, and as the 10 gear segment I4 moves out of engagement with the gear segment I3, said gear segment I4 will move into mesh with the gear segment I2 for reversing the rotative movement of the'shaft II.

The shaft II at the end thereof journaled in 15 the bearing 9 projects beyond the casing of the motor and at its extended end is provided with a squared socket which receives a squared pin I6 formed on the bottom side of a cylinder II. The pin I6 is secured within the socketl I of shaft I I through the medium of set screws or the. like I8.

Fitted within the respective apertured ends of the cylinder I! are bushings I9 which intermediate their ends are provided with flanges 20 that are engaged by flanges on the ends of caps 25 2I and are threaded on'the respective opposite ends of the cylinder II in a manner clear from a study of Figures 3 and 5. In this manner bushings I'9 are securely held within the respective opposite ends of the cylinder I! and accommo- 30 date a rod 22 that extends axially through the cylinder. On an intermediate portion of the rod 22 is a coiled spring 23, the end convolutes of which bear against the inner ends of the bushings I9 and spring 23 serves to absorb the shock, 35 as is apparent.

0n the respective opposite ends thereof shaft 22 is provided with tubular cross-heads 24 which are received between pairs of opposed lugs 25 provided on the machine gun, a portion of which is shown in the drawings and indicated generally by the reference numeral 26.

The lugs 25 are suitably apertured and extending .through the said apertured lugs 25 and the cross-heads 24 are bolts 2! through the medium of which the machine gun is secured to the rod 22.

From the description of the invention thus far, it will be apparent that when the circuit through the electric motor is closed, the drive will be 50 transmitted from the motor through the gearing I4, I3, on one hand, and the gearing I4, I2, on the other hand for oscillating the shaft II and the parts associated therewith in a manner to cause the machine gun 26 to swing first in one 55 direction, then in a reverse direction, or from right to left as the case may be.

It will also be apparent that the gun 26 will be caused to oscillate from the right to the left and vice versa at a rapid rate of speed and accordingly a mounting embodying the features of the present invention will be found especially adapted for use in mounting on airplane machine guns.

For the electric motor there is also provided in accordance with the present invention an automatic starting and stopping switch 29.

In the form of the invention shown in Figures 8 and 9 provision is made for rocking the gun in a vertical plane and to that end instead of providing on the bottom of the cylinder a squared lug as shown and described in the first form of the invention, there extends from the bottom of the cylinder indicated in Figure 8 by the reference numeral ll an arm 29 which at its free end has oppositely projecting lateral arms 30.

Also in this second form of the invention there is provided a smaller supplemental electric motor 3| to one end of the casing of which there is bolted or otherwise secured a gear casing 32 which is provided with a depending lug 33 which fits within the socket of the shaft H as shown in Figure 8. Thus it will be seen that the motor 3| and associated parts will be so'mounted or connected with the shaft I as to oscillate therewith.

On the top thereof the casing-32 is provided with an arcuate slot 34 which receives arm 29 and the lateral ex ensions 30 on the end of the arms are journaled in bearings 35 provided in opposed side walls of the gear casing 32.

On the extensions 30 are gear segments 36 and 31, respectively, and these gear segments are successively engaged and in alternation by a gear segment 38 provided on one end of the armature shaft of the motor 3| as clearly shown in Figure 8.

It will thus be seen that drive from the motor 3| is imparted through the gearings 38 and 36 on one'hand and the gearings 38 and 31 on the other hand for oscillating the arm 29 and consequently causing the gun 21 to swing vertically first to one direction and then in a reverse direction.

It will also be apparent that with the arrangement illustrated in Figures 8 and 9, vertical swinging movement of the gun 26 will take place incidental to an oscillatory movement of the gun in a horizontal plane. I

Thus with a mounting embodying the features of this invention, a machine gun will have a line of fire covering a great area with the result that this mounting, as before mentioned. will be especially useful in mounting machine guns on airplanes for use under conditions of war.
